Description

Technical Field

[0001] This utility model belongs to the field of warehouse management technology, and specifically relates to a lifting baffle system for warehouses. Background Technology

[0002] In the loading and unloading of raw plasma trucks, especially when the transport vehicles arrive at the warehouse for loading and unloading, the reversing and docking process becomes a crucial yet tedious step. Traditionally, drivers rely primarily on manual guidance to complete the reversing operation. This requires close and accurate communication between the driver and ground staff, and also necessitates staff personally getting out of the vehicle or walking around to the rear to manually adjust or connect the barrier located below the warehouse door to ensure the vehicle can accurately reverse to the designated position. This process is not only labor-intensive but also inefficient, susceptible to human error, and increases the risk of operational mistakes.

[0003] More specifically, during the manual connection of the baffle, due to visual and communication barriers between the driver and staff, the contact between the baffle and the cargo compartment is often difficult to achieve a precise and stable state, sometimes only a small contact area can be achieved. This not only affects the stability of cargo loading and unloading, but may also create safety hazards in subsequent operations, such as cargo slipping or the baffle deforming under pressure.

[0004] Furthermore, traditional baffle systems have limited positioning accuracy during reversing, often resulting in the reversing distance exceeding the predetermined position, causing the baffle to tilt up. This further increases the difficulty of loading and unloading goods and may even damage the equipment. Additionally, the side of the baffle fixed to the foundation is usually made of iron, which, while possessing a certain strength and durability, is prone to rust and corrosion when exposed to humid and corrosive environments for extended periods. This not only shortens the baffle's lifespan but also reduces its safety and reliability during use. Utility Model Content

[0005] The purpose of this utility model is to address the deficiencies in the existing technology by providing a warehouse lifting baffle system to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A warehouse lifting baffle system includes a control box, a rangefinder, a rangefinder alarm, and a baffle installed on the foundation below the warehouse door. The top of the baffle is fixed to a drive shaft, and bearings are installed at both ends of the drive shaft. The bearings are fixed to the foundation by fixed brackets. A first drive sprocket is fixed to one end of the drive shaft, and a second drive sprocket is installed below the first drive sprocket. A drive chain is installed between the first and second drive sprockets, and both the first and second drive sprockets are connected to the drive chain. The second drive sprocket is connected to the output end of a motor, and the motor is fixed to the foundation at the location of the second drive sprocket. The rangefinder is installed on the foundation to one side of the first drive sprocket. The rangefinder alarm is installed on the foundation.

[0008] The rangefinder is connected to the input terminal of the control box, while the motor and the rangefinder alarm are both connected to the output terminal of the control box.

[0009] A further improvement to this technical solution is that the rangefinder is an infrared rangefinder of model HFJ6-SL.

[0010] Further improvements to this technical solution include the installation of a sound alarm, a red light alarm, a green light alarm, and a yellow light alarm on the ranging alarm device, all of which are connected to the output of the control box.

[0011] Further improvements to this technical solution include the inclusion of a microcontroller, model STM32F103RBT6, in the control box.

[0012] Further improvements to this technical solution include the addition of a lift button and a lower button on the control box, which are connected to the input terminals of the microcontroller.

[0013] A further improvement to this technical solution is that the surface of the baffle is coated with an anti-corrosion layer.

[0014] The beneficial effects of this utility model are as follows:

[0015] Improved operational efficiency and safety: Based on information from the rangefinder, the system automatically activates the motor to raise and lower the baffle, enabling the baffle to connect with the rear cargo compartment of the vehicle. This process eliminates the need for ground personnel to get off the vehicle or walk around to operate it, reducing manpower consumption and avoiding operational errors and safety hazards caused by human factors.

[0016] Enhanced operational accuracy: The distance measuring alarm provides drivers with clear vehicle position indications through red, green, and yellow lights and audible alarms. When the vehicle reaches a preset threshold distance from the warehouse door, the system can automatically start or stop the barrier lifting, ensuring the vehicle can accurately reverse to the predetermined position, thus improving operational accuracy and stability.

[0017] Extending equipment lifespan: By coating the baffle surface with an anti-corrosion layer, the problem of rust and corrosion caused by long-term exposure to humid and corrosive environments is effectively prevented. This not only extends the service life of the baffle but also improves its safety and reliability during use.

[0018] Flexibility and Adaptability: The system is designed with lift and lower buttons, allowing operators to manually control the raising and lowering of the baffle in case of rangefinder failure or special circumstances. This design enhances the system's flexibility and adaptability, ensuring smooth cargo loading and unloading operations under various conditions.

[0019] Furthermore, the design principle of this utility model is reliable, the structure is simple, and it has a very wide range of application prospects.

[0020] It is evident that this utility model has outstanding substantive features and significant progress compared with the prior art, and the beneficial effects of its implementation are also obvious. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] like Figure 1 and Figure 2As shown, this utility model provides a warehouse lifting baffle system, including a control box 110, a rangefinder 120, a rangefinder alarm 130, and a baffle 140 installed on the foundation 300 below the warehouse door 200. The top of the baffle 140 is fixed to a drive shaft, and bearings are provided at both ends of the drive shaft. The bearings are fixed to the foundation 300 by fixed brackets. A first drive sprocket 150 is fixed to one end of the drive shaft, and a second drive sprocket 160 is provided below the first drive sprocket 150. A [missing information - likely a type of support structure] is provided between the first drive sprocket 150 and the second drive sprocket 160. The transmission chain 170, the first transmission sprocket 150, and the second transmission sprocket 160 are all connected to the transmission chain 170. The second transmission sprocket 160 is connected to the output end of the motor 180, and the motor 180 is fixed on the foundation 300 at the second transmission sprocket 160. The rangefinder 120 is set on the foundation 300 on one side of the first transmission sprocket 150. The rangefinder alarm 130 is installed on the foundation 300. The rangefinder 120 is connected to the input end of the control box 110, and the motor 180 and the rangefinder alarm 130 are both connected to the output end of the control box 110.

[0027] Specifically, the rangefinder 120 is an infrared rangefinder of model HFJ6-SL. The infrared rangefinder 120 can detect vehicle position information and send the detected vehicle position information (distance between the transport vehicle and the warehouse door 200) to the control box 110, which then feeds back to the driver's cab.

[0028] In addition, the ranging alarm 130 is equipped with an audible alarm, a red light alarm, a green light alarm, and a yellow light alarm, all of which are connected to the output of the control box 110. When the transport vehicle is about to reach the warehouse door 200 and enters the recognition area of ​​the infrared rangefinder 120, the ranging alarm 130 starts working and emits an alarm sound to feed back the vehicle's location information to the driver. The driver then parks the transport vehicle at the target location based on the color of the indicator light on the ranging alarm 130 and the alarm sound. Specifically, when the red light alarm of the ranging alarm 130 illuminates (infrared rangefinder 120 detects that the distance between the vehicle and the warehouse door 200 exceeds a first preset threshold) and the audible alarm sounds, it indicates to the driver that the vehicle has not reversed to the target location and still needs to continue reversing; when the green light alarm illuminates (…), the driver is reminded that the vehicle has not reversed to the target location and still needs to reverse; when the green light alarm illuminates (…), the driver is reminded that the vehicle has not reversed to the target location and still needs to reverse; when the green light alarm illuminates (…), the driver is reminded that the vehicle has not reversed to the target location and still needs to reverse; when the red light alarm illuminates (…), the driver is reminded that the vehicle has not reversed to the target location and still needs to reverse; when the green ... If the infrared rangefinder 120 detects that the distance between the vehicle and the warehouse door 200 is less than a first preset threshold and greater than a second preset threshold (the first preset threshold being greater than the second preset threshold), and the audible alarm stops sounding, it indicates that the driver has reversed the vehicle to the target position and needs to stop reversing. If the yellow light alarm illuminates (the infrared rangefinder 120 detects that the distance between the vehicle and the warehouse door 200 is less than the second preset threshold) and the audible alarm sounds, it indicates that the driver has reversed the vehicle beyond the target position and needs to move the vehicle forward. To facilitate reversing the vehicle into the target position, a target position area marker line is drawn on the ground in front of the warehouse door 200.

[0029] In addition, the control box 110 includes an STM32F103RBT6 microcontroller. Based on the distance information fed back by the infrared rangefinder 120, when the transport vehicle is within a first preset threshold distance from the garage door, the microcontroller controls the start motor 180 to lift the baffle 140 via the second transmission sprocket 160, transmission chain 170, first transmission sprocket 150, and drive shaft. After the transport vehicle has reversed to the target position (i.e., when the green light is on), the baffle 140 engages with the rear cargo compartment of the vehicle, eliminating the need for other personnel to get out and direct the reversing operation, thus reducing potential safety hazards. Furthermore, once the transport vehicle is in the target position, a secure engagement between the rear cargo compartment and the baffle 140 is guaranteed (the target position is pre-set). Additionally, after loading and unloading are completed, and the transport vehicle is more than the first preset threshold distance from the warehouse, the microcontroller uses the motor 180 to lower the baffle 140 back to its original position.

[0030] To enable control even during operation, the control box 110 is equipped with a raise button and a lower button, which are connected to the input terminals of the microcontroller. Operators can operate the raise and lower buttons to raise and lower the baffle 140, allowing for continued operation even if the rangefinder 120 fails.

[0031] Finally, since the baffle 140 is generally made of iron, in order to prevent the baffle 140 from corroding and rusting, the present invention coats the surface of the baffle 140 with an anti-corrosion layer, which helps to improve the service life of the baffle 140.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model, but the present utility model is not limited thereto. Any non-creative changes that can be conceived by those skilled in the art, as well as any improvements and modifications made without departing from the principle of the present utility model, should fall within the protection scope of the present utility model.
